Do explosion-proof areas require regular inspections? Which standard specifies this?
In areas with explosive hazards, the installation and use of explosion-proof equipment is a basic requirement. In addition, strict explosion-proof requirements must be met for wiring, grounding, ventilation, penetration through walls, and explosion venting and resistance in such locations.
Do these locations require regular inspections?
Yes. According to the AQ 3009-2007 "Electrical Safety and Explosion-proof Code for Hazardous Areas," in addition to daily inspections, these areas must undergo regular explosion-proof checks by a qualified third-party organization to ensure safety.

ZhongNuo Inspection's on-site explosion-proof inspection service scope:
Explosive gas environments and hazardous areas with flammable or combustible dust in industries or fields such as oil, chemicals, coal, shipping, ports, marine engineering, gas engineering, pharmaceuticals, machinery, textiles, electricity, light industry, grain processing and storage, and wood processing must ensure the anti-explosion safety of dangerous explosive sites to safeguard the economic development of our country and its people.

Do you need a explosion-proof electrical inspection and acceptance report after construction at an explosion-proof site? What standards are followed?
The explosion-proof performance of explosion-proof products is not just about the equipment itself; it also involves the selection of the equipment, installation methods, on-site wiring, and daily maintenance and care practices.
Improper selection and installation of explosion-proof equipment, non-compliance with standard wiring requirements on-site, and daily maintenance that damages the equipment's explosion-proof properties can all lead to the loss of explosion-proof capabilities in the equipment, posing a risk of explosion.
Therefore, the installation and acceptance of the newly introduced explosion-proof equipment is particularly necessary and important.
The explosion-proof acceptance standards are mainly based on AQ 3009, GB/T3836.15, GB/T3836.16, GB 50257, GB 50058, and other standards, with a corresponding explosion-proof electrical inspection report issued.
After the explosion-proof equipment installation and acceptance, it is not a one-time solution. To ensure that the explosion-proof equipment remains in good operating condition and can be safely used in hazardous areas over the long term, continuous supervision and regular inspections of the equipment in use are also necessary.
The interval for regular inspections generally does not exceed 3 years.
ZhongNuo Inspection has provided on-site explosion-proof electrical inspection and explosion-proof renovation services for various gas stations, fuel stations, oil depots, food factories, feed mills, chemical plants, etc., with a wealth of successful cases and industry experience.
